Colts' injury updates following Week 1 of preseason

The Indianapolis Colts might have gotten through their preseason opener unscathed when it comes to their starting quarterback, but they suffered some big injuries at the offensive skill positions.

The biggest injury suffered was to rookie wide receiver Deon Cain, who will miss his first season after tearing his ACL on Thursday night. That is a huge setback, not only for Cain himself but for the wide receiver room as a whole.

In the running back room, Colts head coach Frank Reich told the media Friday in a conference call that both Marlon Mack (hamstring) and Robert Turbin (ankle) are week-to-week with their respective injuries.

As for running back Marlon Mack, he's week-to-week moving forward with a hamstring.

Mack was a favorite to grab the starting role in the backfield while Turbin will serve a four-game suspension once the regular season starts for violating the league’s performance-enhancing drug policy.

Reich also told the media that wide receiver James Wright, who left Thursday night’s game with a knee issue, is also week-to-week.
